Python and virtual environment#

Python 3.10 installation guide#

Note

Python 3.10 is currently the only version that is supported

Download and install the latest version of Python 3.10 from Python.org (e.g. Python 3.10.11).

If this is the only installation of Python on the computer, check the option to add Python to PATH during installation (as shown below). If there are several versions of Python installed, make sure that the correct one is being used when running the application.

It is recommended to disable the path length limit in Windows by clicking the button at the end of the Python installation, as it may prevent errors caused by deep folder structures.
Open a terminal window and run the following command to verify that the python version you just installed is accessible on PATH.
```
>>> python --version
Python 3.10.11
```
